Not really.  Normally, anycasting should be stable; if you send a
request to the same IP address you will get a response from the same
server.  There may be additional load balancing being done where at a
particular location that IP maps to multiple servers (we've done that
with TruCluster for example), but that has nothing to do with
anycasting.
